Further, there are two the lug bosses being oppositely arranged up and down for the setting of linkage section region.
Further, the width of lug boss is 10-30mm, the distance between two lug bosses are 10-20mm.
Further, the top of lug boss is connected by arc transition.
Further, the first guard rail groove profile steel rolling section region and linkage section region connection pass through arc transition
Connection, linkage section region is connect with the second guard rail with groove profile steel rolling section region connection by arc transition.
The present invention another will solve the problems, such as to be to provide a kind of shield that can reduce production difficulty, improve production efficiency
Rail U-steel milling method.
Guard rail provided by the invention U-steel milling method, includes the following steps：
A, steel billet is made by guard rail U-steel roll mill, steel billet is divided into the first guard rail U-steel section, linkage section, the
Two guard rails U-steel section；
B, it is cut by cutter device along linkage section and steel billet is divided into two parts, include that the first guard rail is with U-steel section
It is the second guard rail groove profile steel body that first guard rail groove profile steel body, which includes the second guard rail U-steel section,；
C, the first guard rail groove profile steel body, the second guard rail are polished with groove profile steel body respectively, to obtain two shields
Rail U-steel.
The beneficial effects of the invention are as follows：Roll hole is by sequentially connected first guard rail groove profile steel rolling section region, connection
Section region, the second guard rail are constituted with groove profile steel rolling section region, and the first guard rail groove profile steel rolling section region, the second guard rail are used
Groove profile steel rolling section region is symmetrical set using linkage section region as axis, and the first guard rail is with groove profile steel rolling section region and second
Guard rail with the shape in groove profile steel rolling section region as the shape of guard rail U-steel, the steel billet rolled out by roll hole,
Steel billet is cut into two parts, respectively the first guard rail groove profile steel body, the second guard rail groove profile steel body, by first along linkage section
Guard rail groove profile steel body, the second guard rail are polished with groove profile steel body, to obtain two guard rail U-steels.As it can be seen that in the past
A guard rail U-steel can only be once rolled out, using roll mill and milling method of the invention, can once roll out two
Root guard rail U-steel, improves production efficiency, moreover, roll hole is to be symmetrical set, that is to say guard rail U-steel
Asymmetry becomes symmetry rolling, is convenient for mill operation, reduces production difficulty, improve the quality of guard rail U-steel, benefit
In popularization.
Detailed description of the invention
Fig. 1 is the section structure diagram of guard rail U-steel；
Fig. 2 is the structural schematic diagram of guard rail U-steel roll mill；
Components, position and number in figure：Topping roll 1, bottom roll 2, roll hole 3, the first guard rail groove profile steel rolling section
Region 31, linkage section region 32, the second guard rail groove profile steel rolling section region 33, lug boss 4, guard rail U-steel 5.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Fig. 2, guard rail of the present invention U-steel roll mill, including topping roll 1, bottom roll 2, topping roll 1, bottom roll
About 2 be correspondingly arranged at it is intermediate form roll hole 3, roll hole 3 by sequentially connected first guard rail groove profile steel rolling section region 31,
Linkage section region 32, the second guard rail are constituted with groove profile steel rolling section region 33, and the first guard rail groove profile steel rolling section region 31,
Second guard rail is symmetrical set with groove profile steel rolling section region 33 with linkage section region 32 for axis, and the first guard rail is rolled with U-steel
Section region 31 processed and the second guard rail are with the shape in groove profile steel rolling section region 32 as the shape of guard rail U-steel 5.
Specifically, the shape in linkage section region 32 is axisymmetric shape, for the ease of rolling, loss is reduced, for another example Fig. 2 institute
Show, there are two the lug bosses 4 being oppositely arranged up and down for the setting of linkage section region 32.By being obtained in a large number of experiments and practice, each
The width of lug boss 4 is 10-30mm, and the distance between two lug bosses 4 are 10-20mm.Meanwhile the top of lug boss 4 passes through
Arc transition connection, convenient for rolling.Similarly, the first guard rail groove profile steel rolling section region 31 and 32 connection of linkage section region
It is connected by arc transition, linkage section region 32 and the second guard rail pass through circular arc mistake with 33 connection of groove profile steel rolling section region
Cross connection.
Guard rail provided by the invention U-steel milling method, includes the following steps：
A, steel billet is made by above-mentioned guard rail U-steel roll mill, steel billet is divided into the first guard rail U-steel section, connects
Connect section, the second guard rail U-steel section；
B, it is cut by cutter device along linkage section and steel billet is divided into two parts, include that the first guard rail is with U-steel section
It is the second guard rail groove profile steel body that first guard rail groove profile steel body, which includes the second guard rail U-steel section,；
